Large tonnages of chromite tailing were discarded during processing of chromite ore in the conventional circuit. A typical chromite plant tailing was treated in wilfley table for the recovery of chromite values. Optimisation study was carried out for the process parameters of wilfley table using empirical models, developed from the experimental data.
Mar 06, 2020· The key to avoid recovery losses is to ensure that you install the right flotation solution in your process. Attributes such as innovative tank design, efficient air and level control, proven drive systems with safe and easy maintenance have helped mining companies in achieving higher ore and grade recovery in the flotation cell, while also optimizing energy usage.

What Is The Grade?What Is The Recovery?Grade and Recovery Calculation For A Jigging CircuitCalculation of Grade and Recovery For A Screening, Tabling, Flotation CircuitHead CalculationAn ore contains multiple minerals in combination; its a mixture of valuable components and gangue. The ore grade refers to the fraction of a useful element within the ore. It can also be used for gangue as the proportion of a nonvaluable substance, but generally, when we use the term grade, we mean the grade of a valuable element. For example, a copper ore grade of 1% means that in 100 tons of the ore, we have 1 ton of copper. If tSee more on minerallurgy Published Mar 02, 2021
